[en] This document defines the performance requirements for a graphic display dispatching system to support Hanford Patrol emergency response. This system is defined as a Commercial-Off the-Shelf computer dispatching system providing both text and graphical display information while interfacing with the diverse reporting system within the Hanford Facility. This system also provided expansion capabilities to integrate Hanford Fire and the Occurrence Notification Center and provides back-up capabilities for the Plutonium Processing Facility

[en] An alarm system is a vital component of any accelerator, as it provides a warning that some element of the system is not functioning properly. The severity and age of the alarm may sometimes signify whether urgent or deferred attention is required. For example, older alarms may be given a lower priority if an assumption is made that someone else is already investigating it, whereas those of higher severity or alarms that are more current may indicate the need for an immediate response. The alarm history also provides valuable information regarding the functionality of the overall system, thus careful tracking of these data is likely to improve response time, remove uncertainty about the current status and assist in the ability to promptly respond to the same warning/trigger in the future. Since one goal of every alarm display is to be free of alarms, a clear and concise presentation of an alarm along with useful historic annotations can help the end user address the warning more quickly, thus expediting the elimination of such alarm conditions. By defining a discrete set of very specific alarm management states and by utilizing database resources to maintain a complete and easily accessible alarm history, we anticipate facilitated work flow due to more efficient operator response and management of alarms.

[en] This Decree provides for the setting up of a radioactivity alarm network by the Directorate General for Public Protection to prevent hazards arising from possible incidents originating in nuclear installations. The Duty stations are located in specified police stations and with fire brigades within a radius ranging from 15 to 20 km from planned reactors or nuclear power plants. (NEA)

[en] This patent describes a functional relationship-based alarm processing system and method which analyzes each alarm as it is activated and determines its relative importance with other currently activated alarms and signals in accordance with the functional relationships that the newly activated alarm has with other currently activated alarms. Once the initial level of importance of the alarm has been determined, that alarm is again evaluated if another related alarm is activated or deactivated. Thus, each alarm's importance is continuously updated as the state of the process changes during a scenario

[en] The radiation monitoring instrument generates an acoustic record for the total intensity range of the ionizing radiaiton to be monitored. The human ear identifies a sequence of separate pulses of a given pitch. If the density of the sound pulses of the acoustic record increases the individual pulses become shorter. This is why one gets the impression of a nearly constant physiological volume of sound. The circuit can be assembled from conventional components. The effort is kept especially small if there are used integrated circuits for the frequency divider with bistable steps and the sound generator. (DG)
